It's lunch break. I watched the graph again. It said green area is K-40. But it also said K-40 ND. I don't understand. http://t.co/07LQAmYC

There was an explanation of the guide radiation matter. It's cesium137. 0cm:200microSV, 30cm:1microSV, 60cm:0.3microSV.

They will start lectures about radioactivity, including puppet play.

Beta ray moves zigzag. GeigurCounter counts many times only with one beta ray. Shield and check only gamma ray. http://t.co/DB5F1beL

Bq counter is needed for food radioactive check. http://t.co/8Dcm29ca

Wait before gueger counter stabilized. Avoid shock.(don't hit) Cover with vinyl. http://t.co/LGwzw1vr

ShowEnded!But the technical clame appeared.I mean guigercounter is set for gumma ray. Not Beta ray, but not counted many times,that'sMistake

There are many funny(strange), mistook radioactive check result around in Japan. We need to do accurate checks.

Risks of radioactivity exposure and cancer exist. But how much exactly? Gamma ray is the points. Beta ray is important when food related.

Cheep counter only counts. Expensive one also check about energy level.

Today I mainly talk about cesium. In Food, came from the air,...

Around 0.1microSV/h, cheap GuigerCounter is not suitable. More than 10micro, need low level checker.(Many high grade one's maxLimit is 10SV)

Some GuigurCounter is suitable(best) only for Accumulated value. Talk came into food related radiation exposure.
